Definitions
- the present invention relates to a chewing gum with a prolonged and controlled aroma release while chewing, said chewing gum comprising a conventional chewing gum vehicle and an entirely or partially encapsulated aroma agent.
- a conventional chewing gum comprises in addition to aroma agents (flavourings), also a chewing gum vehicle, which comprises gum base, sweeteners and optionally additional fillers and/or auxiliary agents, such as consistency- adjusting agents.
- EP-PS No. 285 694 discloses polymeric particles for the release of an active ingredient.
- the particles can be incorporated in various compositions.
- the particles are of a spongous, macroporous structure, the completed carrier being provided with a pore network.
- the described process is encumbered with the drawbacks that it is rather compli ⁇ cated and requires two steps. Furthermore, more of the starting materials used have not been allowed for use in articles of food and cannot therefore be used immediately.
- US-PS No. 4,386,106 discloses a method for preparing encapsulated solid flavourant compositions for use in chewing gum, which gives a sustained release of the fla- vourants during chewing.
- the encapsulated flavourants result from preparation of an aqueous emulsion of a fla ⁇ vourant, said emulsion comprising water distillable compo ⁇ nents in a mixture of gelatine, a natural gum, such as gum arabic, and a softener. Subsequently, the emulsion is dried to produce a uniform solid matrix product. The solid matrix product is milled to a particle size less than 20 US mesh, and the resulting powder is coated with a thin layer of polyvinyl acetate, polyvinyl alcohol, zein, ethylcellulose or gelatine having a Bloom of 100 to 300.
- flavourant By the use of the resulting encapsulated flavourant in chewing gum, the flavourant is being released after chewing for 2 to 3 minutes, and the release continues for a period thereafter. As the flavourant is not maintained in the gum base, it is released in an efficient manner, and it is possible to provide the chewing gum with a suitable taste by means of low amounts of flavourants compared to the chewing gums wherein the flavourant is not encapsu ⁇ lated.
- dry flavourant i.e. flavourant dried with gum arabic
- the method is rather complicated because the powder necessitates a finishing treatment for achieving the desired release, and furthermore, it is difficult to reproduce.
- US-PS No. 2,886,446 discloses an encapsulation of flavour ⁇ ings by means of gelatine.
- the encapsulation is carried out by emulsifying the flavouring and gelatine followed by a drying, such as a spray drying.
- the dried emulsion is converted into a powder of ⁇ particle size of 40 to 850 Urn, for instance by way of grinding.
- the gelatine may, if desired, be cured by means of aldehyde.
- the use of gelatine alone as the encapsulating agent allows an increased re ⁇ lease of flavourings with the result that said flavourings can be used in low amounts. Such an intensified release may, however, sometimes cause undesired taste spots, and a harmonious course of the taste is not achieved.
- EP printed accepted specification No. 278,994 discloses a method of controlling the release of flavourants by way of encapsulation.
- the encapsulating material may be starch, saccharose, lactose and other materials.
- the encapsulating materials used without gelatine do not allow a sufficient control of the aroma release for a long period, and accord ⁇ ingly undesired taste spots may be perceived.
- the known porous or encapsulated flavouring- containing compositions cannot stand the mechanical and temperature-related effects, such as kneading and rolling out, usually applying to the preparation of conventional chewing gum.
- the known methods are furthermore encumbered with the problem that the resulting chewing gum discloses a poor storing stability, especially when the flavourings encap ⁇ sulated or bonded in another manner have a higher affinity to the chewing gum base in the vehicle with the result that said flavourings migrate into the vehicle during the storing.
- a too large particle size in proportion to a too low amount of flavouring precludes achieving a homogeneous mixture. Accordingly, it has not previously been possible to ensure a perception of taste without the so-called taste spots, i.e. unpleasant spots of a strong taste like when you chew on a peppercorn.
- the invention relates to a chewing gum with a pro ⁇ longed and controlled aroma release while chewing, said chewing gum comprising a conventional chewing gum vehicle and an entirely or partially encapsulated aroma agent.
- the chewing gum according to the invention is characterised by the encapsulating material comprising gelatine and a polyhydroxy sweetener, said polyhydroxy sweetener compris- ing one or more compounds selected among mono, di and polysachharides and hydrogenated derivatives thereof.
- the aroma agent is available both in encapsulated form and in free form because a particularly homogenous perception of taste is thereby obtained.
- An aroma agent available in free form provides a quickly perceptable taste whereas an encapsulated aroma agent provides the prolonged and con ⁇ trolled release of taste.
- the entire amount of aroma agent may, however, also be available in encapsulated form.
- the polyhydroxy sweetener may for instance be sorbitol, mannitol, xylitol, maltitol, Lycasin TM , lactitol, glucose syrup, fructose, saccharose, lactose and dextrose.
- the polyhydroxy sweetener used in the encapsulation has ex ⁇ clusively a technological function, viz. to assist in controlling the aroma release.
- the polyhydroxy sweetener is thus of no importance as sweetening agent because the amount thereof is insignificant compared to the content of sweeteners in the chewing gum.
- the invention relates furthermore to a process for prepar ⁇ ing the above chewing gum, said process being characterised by
- the process according to the invention allows a controlled speed of the aroma release by changing the encapsulating material.
- it is possible to decrease the speed of release by curing the gelatine, preferably by means of an aldehyde, such as formaldehyde, as well as it -is possible to increase the speed of release by using a higher amount of polyhydroxy sweetener or by using a comparatively easierly soluble polyhydroxy sweetener.
- step b) of the process can be carried out in a conventional manner, such as by spray- drying and/or by drying in a fluid bed.
- the encapsulating material can be incorporated in any type of chewing gum, i.e. both in sugar-containing and in sugar-free chewing gum, in bubble gum and in soft bubble gum.
- the chewing gum may be both coated and not coated and of various shapes.
- the aroma prepara ⁇ tion is present in the core of the chewing gum.
- the encap- sulating material can be incorporated both in medical and in semimedical chewing gum.
- the encapsulated product possesses a high pressure stabi ⁇ lity, which is a property usually measured when a mate- rial is tested for its use in a mass to be compressed into tablets.
- the high pressure stability means that a high stability applies both during the mechanical effects at the preparation and during the mechanical effects during the chewing.
- the product is expected to possess a good storability, where the flavourings do not migrate to the gum base in the vehicle although said flavourings usually display a higher affinity to the gum base.
- flavourings are usually necessary compared to the amount of flavourings necessary when incorporated directly into the chewing gum vehicle.
- the latter proves that the desired sustained release has in fact been ob ⁇ tained because the available amount of flavourings is to be released over a comparatively long chewing period.
- an essential feature of the invention is that the aroma preparation is prepared with a suitable particle size, preferably a particle size in the range of 150 to 210 um. This range together with the used amount of flavourings ensures an excellent aroma release and a pleasant con ⁇ tinued perception of taste without the previously mentioned taste spots .
- a suitable ratio of gelatine to polyhydroxy sweetener must be used. It is, however, not possible to indicate a specific ratio because said ratio depends on the hydrophilic/hydrophobic proper- ties of the individual flavourings and on the desired release.
- the optimal ratio is, however, easily determined by a person skilled in the art by the trial-and-error- method. It is important that the aroma preparation is of a suitable consistency in relation to chewing and saliva so that the encapsulated aroma agents are not released by an explosion of taste in the starting phase, but so that a typical prolonging of the taste with a harmoneous and pleasant taste is perceived.
- Fig. 1 illustrates the taste profile of a chewing gum according to the invention indicated in Example 1,
- Fig. 2 illustrates the taste profile of a conventional comparison chewing gum containing the same flavourings.
- Aroma agent 10% by weight
- the mixing takes place in the following manner.
- the knead ⁇ ing vessels are heated to a temperature of 30 to 80°C, typically 45"C.
- the mixing process begins with kneading a specific amount of gum base for 1 to 20 min, typically for 10 min.
- one or more sweeteners are added either in form of a powder or as a liquid.
- the dosing of sweetener and the following kneading has a duration of 1 to 20 min, typically about 7 min.
- Aroma agents can also be added at the beginning of the kneading process, i.e. before the addition of the sweetener(s) .
- Aroma agents can also be added in two or more portions during the kneading process.
- the kneading vessel is tilted and the gum mass is transferred to trolleys, trays or the like.
- the next step is the shaping of the chewing gum, but before the shaping process the chewing gum must be cooled.
- the chewing gum mass is of a temperature of 50 to 65°C, and in order to allow a shaping of said chewing gum the temperature must be reduced to 30 to 45 ⁇ C.
- the chewing gum is cooled either by storing for a predetermined period in trolleys, on trays or on shelves or by conveying a thin sheet of chewing gum through a cooling tunnel.
- the chewing gum is shaped by means of extrusion through a specially shaped die, or the chewing gum can be shaped after the extrusion by means of rolls, punchers, sizing wheels and the like.
- the chewing gum can be shaped into cores, sticks, balls, cubes, chunks, cylinders and many other shapes.
- the chewing gum In order to prevent the chewing gum from sticking to rolls and other tools, it is powdered with a powder comprising among other ingredients sugar powder, i.e. icing sugar, talc, corn starch and the like.
- the shaped chewing gum can be immediately cooled to room temperature in a cooling tunnel and packed (especially as far as bubble gum and soft bubble gum are concerned) .
- the chewing gum is cooled on trays in intermediary storage at con ⁇ trolled temperatures and humidity.
- the coating pans may be made of copper, stainless steel or polyester reinforced with glass fibers and are often provided with a tubing system for feeding and removing air as well as dosing the coating suspension.
- the coating process is as follows:
- the chewing gum cores are kept in motion inside rotating coating pans. Then the coating suspension is added in small portions being evenly distributed on the surface of the cores. Subsequently, the cores are dried by means of air. The process is repeated up to 70 times until the cores are completely coated and of the desired size and weigh .
- fla- vourings are often added one or more times in order to provide the chewing gum cores with a fast flavour impact during the chewing process.
- the suspension In order to facilitate the coating process of the chewing gum, the suspension is of a temperature of up to 75°C and the air is heated to 40°C.
- the coated product, "candy coated tablets” or “dragees”, are stored for 1 to 2 days and then subjected to the next step, the polishing. It should be noted that the term “candy coated tablets” covers tablets coated with a sugar-containing coating as well as tablets coated with a sugar-free coating.
- the purpose of the polishing is to provide the candy coated tablets with a nice and glazed surface improving the appearance of the tablets as well as their flowing proper ⁇ ties. The latter is important for the subsequent sorting and packing.
- the polishing also takes place in rotating coating pans, where the polishing suspension is added to candy coated tablets in one or more portions.
- the polishing suspension often comprises wax, emulsifier, gum arabic, water or the like.
- Aroma preparation I 0.7 Gelatine 0.4
- Aroma preparation VI 9.8 Flavorings 2.0 Aspartame 0.4 Acesulfam-K 0.2
- the taste profile of the chewing gum according to Example 1 was compared to the taste profile of a conventional comparison chewing gum of the same composition as the chewing gum of Example 1 except for the entire aroma amount being added in non-encapsulated form.
- the comparison was carried out by experts testing the two chewing gums in a blind test. By the comparison tests the experts evaluated the taste qualities stated below according to a scale from 0 to 9 :
- the average values are plotted on a semicircular diagram where 0 is placed in the centre of the circle and 9 is placed at the periphery of the semicircle.
- a graphic illustration of the complicated factors is obtained where the area filled out in the diagram represents a measurement of the taste intensity.
- the diagrams achieved appear from Figs. 1 and 2, where Fig. 1 illustrates the taste profile of a chewing gum according to Example 1, whereas Fig. 2 illustrates the taste profile of the conven- tional comparison chewing gum.
- the diagrams clearly demon ⁇ strate that a prolonged taste release and a more harmoneous and pleasant taste profile is obtained by the chewing gum according to the invention compared to the conventional chewing gum.
- the prolonging of the taste is demon- strated by the parameters F "taste level after 5 min” and E "liquorice peak notes”
- the harmoneous, pleasant and balanced taste is demonstrated by the parameter "li ⁇ quorice sweetness”.
